Fig. 1 is use constitution diagram of the present utility model;
Fig. 2 is that wheel of the present utility model is arranged scheme drawing;
Fig. 3 is car wheel structure scheme drawing of the present utility model.
The specific embodiment
Fig. 1 is use constitution diagram of the present utility model, Fig. 2 is that wheel of the present utility model is arranged scheme drawing, Fig. 3 is car wheel structure scheme drawing of the present utility model, as shown in the figure: chassis is supported in the Monorail PC Track Girders track flexible turnout beam walking of present embodiment, comprise for the chassis vehicle frame 1 that supports the flexible turnout beam and be supported in track 3 and be used for the wheel 6 of brace table vehicle carriage 1 that described wheel 6 follows away direction and is set up in parallel at least two; As shown in Figure 1, flexible turnout beam 2 needs to engage with light rail track 4 and light rail track 5 according to mode of operation, the brace table vehicle carriage 1 that chassis is supported in walking is supported on flexible turnout beam 2 bottoms, quantity is decided according to the length of flexible turnout beam 2, and the longer support chassis that then needs of length is more.
In the present embodiment, the track center of circle the when wheel axis 61 of described wheel 6 is passed through flexible turnout beam flexible deformation; So that the installation of wheel 6 is adapted to the flexible deformation's of track switch beam path of motion, namely form certain central angle between the wheel axis 61 of wheel 6, when avoiding moving and track interfere friction, be easy to increase the service life.
In the present embodiment, described wheel 6 is arranged at wheel shaft 14 by antifriction-bearing box 12, and described wheel shaft 14 is supported in chassis vehicle frame 1; As shown in the figure, wheel shaft 14 is supported in the chassis bottom of frame by axle block 13, and is simple and compact for structure, and stability of strutting system is good.
In the present embodiment, described wheel 6 axial two ends are respectively equipped with wheel hub 11, described wheel hub 11 is fixedly connected on wheel 6 and cooperates in the circumferencial direction dynamic seal with wheel shaft 14 at circumferencial direction, as shown in the figure, seal by O type circle between wheel hub 11 and the wheel shaft 14, also can adopt common shaft seal to seal; Wheel hub 11 adopts the annular slab structures, is formed for antifriction-bearing box is radially formed lubricated cavity, guarantees that the smooth and easy long period of wheel uses.
In the present embodiment, described wheel shaft 14 has oil inlet passage 7 vertically, and this oil inlet passage 7 is communicated with the annular seal space 15 that wheel hub 11 by wheel 6 axial two ends forms, and wheel hub 11 is provided with oil outlet 10; Realize the lubricated of wheel 6 by these oil inlet passage 7 oilings, and utilize the oil outlet 10 on the wheel hub 11 to discharge excessive fuel consumption, easy to use, do not change oil after not needing to take apart, guarantee its normal use.
In the present embodiment, described wheel 6 is arranged at wheel shaft by two aligning antifriction bearings arranged side by side vertically, guarantees that wheel has the effect that self adaptation is adjusted the orientation, thereby makes its operation smooth and easy without interfering.
In the present embodiment, the inner ring of described aligning antifriction bearing is arranged at wheel shaft 14 by the axle sleeve 16 that interference fit is coated at wheel shaft 14; Axle sleeve 16 adopts interference fit with the inner ring of aligning antifriction bearing, axle sleeve 16 can adopt free-running fit with wheel shaft 14, because the coefficient of rolling friction of antifriction-bearing box 12 will be much smaller than the coefficient of sliding resistance of axle sleeve and wheel shaft, this structure does not affect normal operation, and be beneficial to assembling, change and maintenance, increase work efficiency, avoid track traffic because Wheel maintenance etc. are former thereby stoppage in transit.
In the present embodiment, described oil inlet passage 7 is opened in the axle center of wheel shaft 14, and is communicated in the annular seal space 15 of wheel hub 11 formation at wheel 6 axial two ends by the radial passage; The import of oil inlet passage 7 is positioned at wheel shaft 14 1 axial end portions and is provided with for the deep gouge 9 that embeds zerk 8, forms the protection structure of zerk 8, and zerk 8 is not damaged by the external world.
In the present embodiment, wheel shaft 14 surfaces have chromium coating, because this wheel shaft 14 need bear larger stress, the general alloy steel forging that adopts causes, and heat-treat to guarantee the intensity of axle, chromium coating can prevent that this axle from being corroded by the external world, both guaranteed the intensity of this axle, prevent that again this axle from getting rusty, and hard chrome has again wear-resisting characteristic.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
